Question

match the formula with its compound name.
co is the formula for select .
n₂o₅ is the formula for select .
h₂o is the formula for select .

Explanation:

Step1: Analyze CO

Carbon monoxide (CO) is a compound with one carbon and one oxygen atom. So CO matches with carbon monoxide.

Step2: Analyze \( \boldsymbol{N_2O_5} \)

Dinitrogen pentoxide has 2 nitrogen atoms and 5 oxygen atoms, so \( N_2O_5 \) is dinitrogen pentoxide.

Step3: Analyze \( \boldsymbol{H_2O} \)

Water has 2 hydrogen and 1 oxygen atom, so \( H_2O \) is water (or dihydrogen monoxide).

Answer:

• CO is the formula for carbon monoxide.
• \( N_2O_5 \) is the formula for dinitrogen pentoxide.
• \( H_2O \) is the formula for water (dihydrogen monoxide).
